+ <title>Ruby: Terminal Control Character Injection</title>
+ <synopsis>
+ An input sanitation flaw in the WEBrick HTTP server included in Ruby might
+ allow remote attackers to inject arbitrary control characters into terminal
+ sessions.

+ <background>
+ <p>
+ Ruby is an interpreted scripting language for quick and easy
+ object-oriented programming. It comes bundled with a HTTP server
+ ("WEBrick").
+ </p>
+ </background>
+ <description>
+ <p>
+ Giovanni Pellerano, Alessandro Tanasi and Francesco Ongaro reported
+ that WEBrick does not filter terminal control characters, for instance
+ when handling HTTP logs.
+ </p>
+ </description>
+ <impact type="normal">
+ <p>
+ A remote attacker could send a specially crafted HTTP request to a
+ WEBrick server to inject arbitrary terminal control characters,
+ possibly resulting in the execution of arbitrary commands, data loss,
+ or other unspecified impact. This could also be used to facilitate
+ other attacks.
+ </p>
+ </impact>
+ <workaround>
+ <p>
+ There is no known workaround at this time.
+ </p>
+ </workaround>
+ <resolution>
+ <p>
+ All Ruby 1.8.7 users should upgrade to the latest version:
+ </p>
+ <code>
+ # emerge --sync
+ # emerge --ask --oneshot --verbose &quot;&gt;=dev-lang/ruby-1.8.7_p249&quot;</code>
+ <p>
+ All Ruby 1.8.6 users should upgrade to the latest version:
+ </p>
+ <code>
+ # emerge --sync
+ # emerge --ask --oneshot --verbose &quot;&gt;=dev-lang/ruby-1.8.6_p388&quot;</code>
